Learn more about the ingenious clocks made by John Harrison to help sailors determine their longitude at sea, drastically reducing the danger of ships, crew, and cargo being lost to the waters. The clocks themselves look incredibly sophisticated and beautiful. There are four versions of the clocks, H1 to H4, the H1 having been released in 1735. Along with others, it was widely heralded as a great milestone in the history of clock-making. Take the chance to stand beneath the Great Equatorial Telescope, a 28-inch refracting telescope that is the largest of its kind in the UK. Originally designed for astrophotography, it has become indispensable for the observatory's research into double stars. Don't miss out on seeing the telescope's distinct "onion roof" when you look up at the Royal Observatory.
